DUST RECEPTAGLE FOR'VACUUM CLEANERS.

Application filed May 17, 1920. Serial No. 382,107.

To all whom it may concern:

Be it known that I, FRANK J. Dawson, a citizen of the United States, resldent of Cleveland, county of Cuyahoga, and State ciple, so as to distinguish it from other inventions.

My invention relates to vacuum cleaners, and particularly to a new and improved receptacle for the dust and dirt collected by such cleaners. More particularly, my invention relates to such a receptacle from which the contents may be easily and effectively discharged, without the necessity of detachin the receptacle from the machine. g

Fhe annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of the various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings:

Figure 1 represents a front elevation of my new and improved apparatus;

Figure 2 represents a side elevation thereof;

Figure 3 represents an enlarged end elevation of mechanism for actuating a door controlling the discharge of the contents from the receptacle, said view being taken in the plane indicated by the line III-J11, Figure 2;

Figure 4 represents an enlarged side elef vation of said door-actuating mechanism Figure 5 represents an enlarged plan view "of the partsshown in Fi ures 3 and 4, taken in the planes indicated y the lines V-V, Figure 2; p

Figure 6 represents an enlarged rear elevation of a special metal dust receptacle, said view beingtaken from the plane indicated by the line VI-VI, Figure 2;

Figure 7 represents a vertical section taken in the plane indicated by the line VII-VII, Figure 6 v Figure 7 is an enlarged fragmentary section of certain elements shown in Figure 7 particularly showing the method of securing the mar 'nal edge of the fabric bag ad a- "cently t e edge of the opening in a metal receptacle with which an opening in the said fabric bag registers;

Figure 8 represents an enlarged side view of the metal dust-collecting receptacle and co-operating parts; and

Figure 9 represents a plan section of the parts shown in Figure 8, said section being taken in the plane indicated by the line IXIX, Figure 8.

Referring to the annexed drawings, there is lndicated by the ordinal 1 a suitable body, motor and other co-operatingparts of any vacuum cleaner of standard-design, the same being rovided with an operating handle 2 and a abric bag 3. Said bag 3 is of special design, according to the type of vacuum cleaner to which it is designed to be attached, and co-operates with a metal compartment 4 having an open side 4 adapted to register with an opening 3 in said fabric bag. The edges of said bag and receptaclev 5, said arms 7 being pivoted exteriorly of the receptacle 4 upon the rod 6. One of these arms 7 is formed with an extension 7 pivoted at its outer end'upon a pin 9' secured in a ferrule 20 mounted upon a rod 9 and adjacently one end thereof, said rod being secured at its other end and adjacently the upper end of the handle 2 to a yoke 10 between the arms of which is pivoted an extension 12 of a manually operable grip 11. The extension 12 of the grip 11 is pivoted upona pin 13 secured to a downwardly extending extension 15 of a bracket 14, which is secured to the handle 3 adjacently the upper end thereof by means of a clamp 16 and screws 17 The rod 8, to the ends of which the arms 7 are secured, is adapted to register with elongated recesses 4" formed in the bottom edges of the side plates of the metallic receptacle 4, said door 5 also being formed with an upturned marginal flange 5 adapted closely to register with the rear and si e walls of the box 4, so as tightly to adjacently t'he slot-12 close the door opening. Furthermore, felt padding 27, plainly shownin Figure 7, is also provided adjacently the closing edges of the door 5 for securing a tight joint.

The opening and closing of the door 5are controlled through the actuation of the grip 11. When the gri 11 is released from. a. detent hereinafter ully described, the door 5 is adapted under the influence of gravity, to be slightly opened, and when the grip 11 is restrained by the detent, the door 5 positively is. held closed. This resultis obtained by the provision of an abutment 19, provided at the extreme lower end of the rod 9 and a sleeve 20 loosely mounted on the rod 9 somewhat forwardly of the abutment 19. a collar 20' secured to' the rod 9 somewhat forward of the sleeve 20, and a spring 18 disposed intermediate the abutment 19 and the sleeve 20. The pin 9 is fixed to the sleeve 20. The relative arrangement of these 'details and the tension of the spring 18 are such that, when the rod 9 is held in its uppermost position, by means of the detent hereinafter described, the spring 18 will force the sleeve 20 upwardly an amount necessary tightly ,to close the door 5, before the sleeve 20 reaches the-fixed collar 20.

-This condition is plainly illustrated in Figures 2 and 8, where the slight clearance between the sleeve 20 and the collar 20' isindicated by the ordinal 20 When the rod 9 is released from the detent, the tension of spring 18 upon the abutment 19 will force the rod 9 downwardly until the collar 20 strikes the sleeve 20, also, the excess weight of the rod 9, over and above the weight of the grip 11, "and the pull of gravity upon the door 5, will cause the door slightly to open. The clearance area 20 will allow for any irregularities of workmanship, which would tend to prevent the tight closing of the door 5 and also will allow for any wear upon the felt padding 27. In order that the door 5 may be maintained closed, the following detail forming a detent is provided. There is formed in the extension 12 of theigrip 11 a slot 12 adapted to receive a catch 22 formed upon a trip 21, said tripbeing a pin 21 secured upon a right-angular extension 15 of the member 15, said trip being normally held so that the catch 22 may engage the slot 12 by means of a spring 23 secured to the angular extension 15 and adjacently'the outer end of the trip-21. In order that the catch 22 may automatically engage with the slot 12 when the-operating grip member 11 is swung upon the pin 13 inwardl toward the handle 2 to the position shown in Figure 4, the lower edge of the catch 22 is formed with a beveled surface.

22, and the upper edge of the extension 12 is formed with a beveled surface 12 by means of which surfaces the catch 22 is forced slightly ivoted upon to the sides of thehandle 2, to a marginal angular extension 4* of the bottom plate 4, of the receptacle 4, as plainly shown in Figures 7 and 9. The bolts 25 pass through said marginal edge 4 and clamped between the bolt heads and said edge 45* and upon both sides of the latter are short bearing plates or strips 29, plainly shown in Figure 9.

The fabric 3 defining the opening leading into the receptacle 4, 'as well as the metal defining the opening registering with said fabric opening, are secured together in a distinctive manner, which will now be described in detail. The metal which defines this opening consists of the upper edges of the side plates 4 of the box 4, the angular extension 4 and a narrow metallic plate disposed transversely of the receptacle and adj acently the upper edge of the door 5 and denoted by the ordinal 4 A transversely arranged rectangular frame is carried at the upper end of, the receptacle, shown in section at 26, Figure 7 and the fabric is turned down over this frame and then the upper edges of the receptacle sections 4 4C and 4 are turned over and under the fabric to secure a tight joint, as plainly shown in Figures 7 and 7. In other words, the frame 26 and the fabric 3 are first assembled and then this assembly incorporated with the metal sections 1-, 4 and 4 of the receptacle or box 4.

A contracted neck 3 is indicated by the ordinal 3', the same being formed so as to be adapted to be attached to the desired type of machine 1 to receive the dust and dirt therefrom, as plainly shown in Figure 1. By means of the hook 28 secured to one end of the member 14, adjacently the top of the operating. handle 2, the bag 3 is held supported in an extended condition, as plainly shown in Figure 1.
